CHICAGO HEIGHTS, ILLINOIS, A GOR- WARM-AIR REGISTER.

SPECIFICATION forming part of Letters Patent No. 749,065, dated January 5, 1904. Application filed February 24, 1903. Serial No. 144,796. (No model.)

To all whom, it may concern.-

Be it known that I, THOMAS E. HUNT, a citizen of the United States, residing in Blue Island, in the county of Cook, State of Illinois,

have invented certain new and useful Improvements in Warm-Air Registers, of which the following is a specification.

This invention relates to registers adapted for use in the walls of rooms, and is so ar- I0 ranged that the Warm air from the register may be deflected and thrown out into the room, if so desired, or may be shut off from the room and carried up in the main pipe to the room or rooms above or may be regulated to divide the warm air, deflecting'some and allowing the rest to pass up.

The register of this invention is constructed so as to be strong and durable without being expensive and so as to be easily inserted into place within the wall when so desired.

The invention consists of the features of construction and combination of inafter described and claimed.

In the drawings, Figure 1 is a front view of the register, showing the door open for the purpose of deflecting the warm air into the room; Fig. 2, a back view of the register; Fig. 3, end elevation; Fig. 1, cross-sectional view taken on line 4 4 of Fig. l with the knob for operating the door omitted; Fig. 5, a top or plan View with the front plate or frame removed; Fig. 6, an end elevation with the front plate or frame removed and the casing partly broken away; Fig. 7, a perspective view of one of the corners of the front cross-bar; Fig.

- 8, a top View of the cross-bar; Fig. 9, a' detail of the arm or lever for controlling the movement of the door or deflector.

The register of this invention is constructed 40 to have a shell or casing A, preferably constructed of sheet metal and having end walls A and a connecting rear wall A formed of the same sheet of metal as the end walls, the end walls being forwardly-turned projections of the rear wall, and the shell or casing is further provided with an obliquely-disposed top a, preferably composed of the same sheet of metal as the rear wall and provided with an opening extending through it, and the top is parts hereprovided on its ends with downwardly-turned so overlapping strips a, which are riveted, by meansof rivets a to the top edges of the end walls, the lower corner a of said strips being cut away to allow the same to be turned down to overlap the end walls, as heretofore described. In the sloping top is cut a rectangular hole B, and from the material composing the top are turned end flanges b, an upper flange b, and a lower flange 19 which form, in effect, a short neck for the attach- 6o ment thereto of the collar, from which the upward-extending pipe leads. It will thus be seen that the end walls, the rear wall, and the top of the box or casing are all made of a single piece of sheet metal without the 6 necessity of soldering or brazing, thereby greatly simplifying the construction of the register as a whole and at the same time making it lighter and more durable than would otherwise be the case. The warm-air pipe may. lead directly from the flanges, if so desired, and the collar dispensed with. The lower edge of the rear wall is given an upward turn 0 and a reverse'turn c, leaving a longitudinally extending groove 0, which serves as a socket for the adjustment of the register to the warm-air pipe for which it is intended. The edges of the end walls of the box or casing are likewise given an upward turn D and a reverse turn d, leaving a groove d extending across each end of the box or casing similar to the groove 0, which extends between the two end grooves. The front lower edges of the end walls are connected by means of a bar E, (shown in detail in Figs. 6, 7, and 8,) and said bar is provided with a forwardlyextending flange e on its top and with rearwardly-extending wings e, which are secured to the outer faces of the end walls by means of rivets e or otherwise, thereby uniting the front lower edges of the box or casing firmly together and preventing the ends from being sprung out of shape by pressure thereon. The lower edge of the bar and of the rearwardly-turned wings is folded backon itself, 5 and along the front of the bar said edge is given a reverse turn 6 forming a longitudinally-extending'groove 6 which, in conjunction with the end grooves,completes the socket for attachment of the register to the supplypipe and enables the register to be quickly and easily slipped into place on top of said pipe and there held by its own weight without the necessity for further fastening means. The end wings e are slipped back between the upwardly-turned edges of the end walls and the outer faces of the end walls and well riveted, as heretofore explained, strongly reinforcing the entire box at the corner and provide four thicknesses of metal at this point without counting the reverse turn of the edge which forms the socket. The front edges of the ends are cut to have a vertical edge F and an oblique edge f, extending upward therefrom, so that the front face of the register while well inserted into place will project outwardly from the wall at its 10 wer edge and lie practically flush with the wall at its upper edge.

In front of the box or casing is a front frame G, having a lower closed section G and an open upper section G set at an angle oblique to the lower section, and the upper section has on its front face an outwardly-turned circumferential ridge g, while the lower section has a similar ridge g, forming, in eifect, a continuation of the ridge g, and said ridges are connected by means of a cross-ridge g and the ridges on theininner or opposite sides form channels g and 9 The front frame is provided with end walls H, consisting of a front section 7t and a rear section It, extended laterally beyond the plane of the front section, forming a shoulder h in conjunction with the front sections, and the rear sections are united to lower sections h which form, in conjunction with the front sections, ledges h.

The box or casing is attached to the front frame by means of angle-plates I, which are riveted, by means of rivets i, to the outer faces of the end sections of the box or casing and are provided at their forward ends with inwardly-turned flanges i, which abut against the inner face of the lower section of the front frame and are secured thereto by means of screws 2' and nuts 4?, thereby holding the box or casing into firm contact with the front frame and holding the front edge of the box or casing within the circumferentially-extending groove or recess 9 thereby rendering the front frame practically integral with the box or casing and holding the forwardly-turned flange e of the cross-bar within a groove or recess g in the lower edge of the front frame without the necessity for further securing the sections of the register together. The continuous contactof the front edges serves to prevent the displacement of the box or casing. The front frame is provided with a top cross-wall G which serves to unite the end walls and strengthen the entire frame.

On the top of the box or casing is a rectangular neck J, having end walls J, a short front wall J and a long rear wall J thereby providing a flat top edge and the obliquelyformed lower contact edge for contact with the top of the box or casing, and the rear wall is provided with an obliquely-extending flange or ledge j, having a downwardlyturned edge or rim j, which edge or rim forms a reinforcement for the rear upper corner of the box or casing and is secured thereto by means of a screw j passing through a lug 9' and through the rear wall and being held by means of a nutj, thereby uniting the rear wall to the rectangular collar, and the latter is united to the top of the box or casing by means of end screws K passing through end flanges 7t and by means of a top screw passing through a top lug It will thus be seen that the rectangular collar is thoroughly attached to the top of the box or casing and securely held in place thereon by means of the screws and by means of the upwardly-turned flanges b, b, and 19 which contact the inner walls of the collar.

The front frame is provided with a door L, which is adapted to close the open space in the upper section of the front frame, and said door is fastened at its top by means of fiat spring-hangers Z, secured to the door by means of screws and nuts l, and the upper' ends of the springs are attached, by means of screws L and lugs Z in the groove or channel g The springs are secured to the door at sufiicientdistance below its upper edge to allow of considerable play or movement in the spring, which arrangement is necessary to prevent the spring from being worn out or broken by continuous bending at a single point. The door is provided on its lower edge with a suitable knob L, formed of coiled wire, for the purpose of opening and closing the door, and the lower edge of the door is adapted when closed to abut against the inner edge of the cross-ridge g, as shown in Fig. 4. Within the box or casing is a grate M, having a surface which may be flat or of any suitable curvature, since it is not necessary that the curvature conform to the swing of the door, which does not contact therewith, and said grate is provided with a lower or front cross-bar m, an upper or rear crossbar m, and connecting grate-bars m as is usual in the construction of grates. The lower bar is provided on its center with a downwardly-projecting lug mithrough which passes a screw m which secures the grate to the front of the frame at a point just below the cross-groove g The rear cross-bar of the grate does not abut against the rear inner wall of the box or casing, as it is not necessary to secure the grate at this point. As shown, the lower edge of the door is adapted to swing out of contact with the upper face of the grate,.and in order that the position of the door may be regulated in use a swinging arm or lever N is provided,which is attached at its-upper end by means of a pivot n to a lug n on the inner face of the door, and the arm of the lever N is provided with a slot n through which passes a screw-threaded pivot-pin n having a head M, which contacts a washer 12 outside of the arm or leverand passes through a lug n on the end grate bar of the grate, and the screw-threaded pinis provided with adjusting-nut n between which and the lug on the end grate-bar is a coil-spring a by which the contact between the arm and the end bar may be tightened or loosened, thereby regulating the ease with which the door can be opened or closed and causing the door to maintain its regulated position without contact with the top face of the grate. As the door is swung the slotted arm moves on the pivot-pin n to accommodate the change in distance between the pivot-pin n and the pivot 12, which change is incident to the movement of the door. The slot in the arm allows the bolt to travel up and down therein as the door is moved, and when the spring has been tightened or tightly compressed by means of adj usting-nut, the freedom of travel of such arm along the bolt will be lessened, thereby more tightly holding the door in any adjusted relation. Moreover, by this means the door is enabled to work noiselessly, since it is not held in contact with the top face of the grate, along which it would otherwise scrape when moved.

It will thus be seen that the register as a whole is one which may be entirely assembled at the factory and easily inserted into place on a warm-air pipe without necessity for any means of attachment other than the flange around the lower edge of the box or casing and that when so placed a solid and substantial neck is provided for attachment thereto an upwardly-extending warm-air pipe leading to the room or rooms above. When it is necessary to send out all the warm air into the room in which the register is located, the door is entirely opened, as in Fig. 1, causing the lower edge of the door to abut against the rear wall of the box and entirely close the opening through the top of the box, thereby forming an obliquely-disposed deflector to send out all the warm air into the room and allow none of it to travel upward. When it is desirable to divide the current of warm air, the same may be done by partially opening the door, which maintains its adjusted position by reason of the action of the slotted arm or lever, and in this position a portion of the air will be deflected into the room, while the remainder of the air will pass up through the pipe, and when it is desirable to send all of the air up through the pipe the door may be closed, as in Fig. 4, and none of the air allowed to escape into the room.

It must be seen that the register is simple in construction, strong, and durable. It is composed of but few parts, the entire register having but six distinct pieces of metal in lits construction, not counting the bolts or other connecting devices.

What I regard as new and desire to secure by Letters Patent is 1. In a warm-air register, the combination of a box or casing, provided with a rear wall, end walls and a top extending obliquely upward from the rear wall; a socket formed on the lower edges of the Walls by giving the metal thereof an upward and a reverse turn; a collar attached to the obliquely-disposed top; a front frame provided with a, circumferentially-extending groove or recess, into which the front edges of the end walls and top of the box or casing are adapted to fit, the frame being provided with an opening in its upper section; a grate within the box or casing, and a swinging door secured at its upper edge and adapted to swing within the box and above the grate for regulating the passage of air through the register; a slotted arm pivoted to the door and slidably attached to the grate for holding the door in adjusted position with respect to the grate, substantially as described.
